After you connect a headset to your phone, you can set up your phone to use the headset automatically 
when answering and placing calls.
For setup information on how to connect a headset to your phone, see the Quick Start Guide for your 
phone on the Business Media Phones Support page.
Note:  If your phone does not detect the USB headset when you attach it to your phone, the USB port on 
your phone may be disabled. Contact your system administrator.
Use Your Headset for All Calls
You can set up your phone so that all incoming and outgoing calls automatically use your headset. To 
use this feature, you must enable and activate Headset Memory Mode.
Procedure
1. Navigate to Settings >Basic > Preferences > Headset > Headset Memory.
2. From the Headset Memory Mode screen, select Enabled.
3. Press the headset key twice.
The headset key flashes to indicate that Headset Memory Mode is now activated. All calls placed 
or answered on your phone use your headset automatically.
Note:  If you or your contacts experience audio or echo issues during calls, such as feedback of 
your voice or of their own voice, you need to enable echo cancellation on your phone.

Using Electronic Hookswitch
When you use a headset that supports electronic hookswitch (EHS), you can place, answer, and end 
calls by using the controls on your headset. To use EHS, you need a headset that includes a serial 
control interface in addition to the standard analog headset jack (RJ-9) interface. The serial control 
interface requires an EHS adapter that you can purchase from your headset manufacturer.
Headsets that support EHS include a base unit that connects to your phone. The headset connects to the 
base unit wirelessly, which enables you to use your headset even if you're some distance away from your 
phone. Typically, you can work wirelessly up to 300 feet (91 meters) from your phone and still use the 
EHS controls. Check with your headset's user guide for the precise range restrictions.
